The boss or manager of Ampang Yong tau hoo along East Coast Road is arrogant. They have lousy service n do not accept 5 cents coins. I thought 5 cent is legal tender in Singapore. My bowl of Ampang Yong tau hoo cost $9.80. I paid with notes n 2 five cents coins. But the boss/manager crudely rejected my 5 cents coins. I left without eating. Shall we boycott them?
